Abstract: 819,250. Moulding plastic containers. COLE Ltd., E. K., and SMITH, B. Aug. 28, 1957 [Aug. 30, 1956], No. 26469/56. Class 87(2). [Also in Group I] A plastic container, e.g. a colander or sink tidy having at least one side wall perforated, is moulded as a blank with its side walls A-D including the perforated wall or walls, all lying in substantially the same plane and with flexible junctions E between them, so that by bending about the junctions, they may be assembled to form the side walls of the container. In the high-density polyethylene moulding shown, for a sink tidy the outer portions A and D brought together produce one side wall, the other two walls B, C being at approximately 90 degrees to each other. Flanges M, N on the portions A, D are held together e.g. by the engagement of suitable fixing means, e.g. integrally moulded press studs P on one flange in holes R in the other or by adhesive or welding. Each portion A-D has projecting at right angles to it an integrally moulded sector-shaped wall which together form a bottom for the container. The flexible junctions E have stiff ribbed projections S extending from them to form legs for the container.

Title: Improvements relating to pressure controlling or cushioning appliances
IPC: B21D24/02
Filed: 1953-09-26
Abstract: 769,308. Cupping. BRETTELL, Ltd., T. & J., and CARTER, A. Dec. 23, 1954 [Sept. 26, 1953; Oct. 8, 1954], Nos. 26539/53 and 28994/54. Class 83 (4). [Also in Group XXIX] Means giving a controlled resisting pressure to the downward movement of the draw ring 3 of a press for the cupping of sheet metal articles from blanks, comprises a main ram 2 in a cylinder 1 which during a working stroke of the press forces liquid into an intensifier cylinder 10 to displace a piston 12 connected to a larger piston 15, thus compressing air in a cylinder 16. The air thus compressed serves to restore the displaced liquid to the cylinder 1 when the applied force on the ram 2 is relieved. A oneway throttle prevents too rapid a return of the ram 2. To compensate for leakage from the cylinders 1, 10, the piston 12 has an axial bore 25 containing a stationary piston 26. The space above the piston 26 communicates with a reservoir 29, and the space beneath the piston communicates with the space above the piston 12 through a port 34, bore 33 and non-return valve 35. On a downstroke of the piston 12, the spaces above and below the piston 26 intercommunicate through a passage in the piston 26; on an upstroke of the piston 12, when the passage through the piston 26 is closed by a narrow part of the bore 25, the liquid beneath the piston 26 is forced into the cylinder 10.

Title: Adhesive system for attaching cured fluorocarbon elastomers to metals
Inventor: BOTHAM GEORGE HENRY
IPC: C09J163/00
Filed: 1961-07-25
Abstract: A fluorocarbon elastomer, e.g. a copolymer of hexafluoropropylene and vinylidene fluoride, is secured to a metal by the use of a rubber- or synthetic rubber-phenolic resin adhesive applied to the metal in conjunction with an epoxy resin applied to the fluorocarbon.  The rubber used may be natural, GRS, or nitrile rubber.  The adhesives are preferably applied in solution in a solvent such as methyl ethyl ketone with or without a proportion of a non-inflammable solvent such as trichloroethylene, and may contain dyestuffs.  In an example a solution in methyl ethyl ketone of a composition containing 100 parts of nitrile rubber, 140 parts of phenolformaldehyde resin and 14 parts of hexamine is applied to a metal surface and dried; a second solution, in the same solvent, of an epoxy resin is then applied and the fluorocarbon layer applied when the coating has dried to the tacky stage; the joint is then cured in hot air or steam at 120 DEG C. for 30 minutes.  The invention is applicable to the adhesion of fluorocarbon gaskets to metal plates in heat exchangers, for example those forming part of dairy equipment.

Filed: 1925-10-28
Abstract: 242,291. Thomas, A. G. Oct. 31, 1924, [Convention date]. Blind persons, teaching and communicating with. -Printed or manuscript characters are reproduced in relief by a series of movable rods or pins, each of which is controlled by a selenium cell. The pins 14, Fig. 2, are guided within a partitioned frame of the form shown in Fig. 3, and are normally held elevated, with their ends in the same plane, by means of pivoted armatures 12 controlled by electromagnets 11 in series with batteries 2<11> and resilient members 9 which normally hold two points 10 in contact. The selenium cells 6 are arranged to form a screen 5, Fig. 1, each cell being supported by clips 7 which connect it in series with a battery 2' and relay 8. A lens 4 is positioned between the screen 5 and the sheet bearing the printed &c. characters 3, with the result that the characters are reproduced by the elevated pins associated with the inactive cells covered by the image of the characters, the increased conductivity of the surrounding cells causing their relays 8 to become energized to break the circuits of the electromagnets 11, thereby releasing the armatures 12 and allowing the pins 14 to fall. Other lightresponsive devices capable of actuating an electromagnetic relay can be substituted for the selenium cells.

Title: Improvement in piezoelectric crystal means and method of using same
IPC: H03H9/17
Filed: 1945-10-16
Abstract: 634,775. Piezo-electric crystals. BRUSH DEVELOPMENT CO. Oct. 16, 1945, No. 27112. Convention date. June 8, 1944. [Class 40 (v)] [Also in Group XL (b)] A piezo-electric body is composed, apart from impurities, of primary ammonium phosphate, and has a pair of parallel electrodable surfaces perpendicular to the Z axis of the crystal. Fig. 2 shows a mother crystal 15 from which plates 17 and 27 may be cut. If electrodes are applied to the major surfaces of plate 17 a surface shear plate is produced in which expansion and contraction takes place along the diagonals as shown by arrows in Fig. 4. From this plate may be cut an expander plate 25 having its major dimensions parallel to the diagonals of plate 17. When electrodes are applied to the minor end faces of plate 27, Fig. 2, the mode of vibration is a pure shear controlled by the smallest dimension of the plate. If the Z dimension of the plate is reduced the capacity is increased without substantially altering the frequency. Two expander plates 25 may be joined together face to face with an interposed electrode to form a bender unit for driving a loud-speaker (Fig. 10, not shown). A Z-cut shear plate 17 may be used as in Fig. 11 to drive a loudspeaker diaphragm 91, the lower edge of the shear plate being fixed to a base 90. Two shear plates may be joined face to face to form a twister element 51, Fig. 13. One edge and the centre line are held clamped between rubber pads 52, 53. The free end then executes a pure twist, and may be coupled by rod 54 to the stylus of a gramophone pick-up or record cutter as described in Specification 521,435. Specifications 318,934, [Class 40 (v)], 569,285 and 600,853 also are referred to. The Specification as open to inspection under Sect. 91 also includes the following matter. Fig. 8 (Cancelled) shows plates 37, 38 cut at angles of 45 degrees to the faces of a block 36 which is cut with its faces at 45 degrees to the major faces of the mother crystal. Plates 37, 38 are stated to be thickness expander plates. Reference is made to mixed crystals formed by the addition of the phosphates and arsenates of rubidium, caesium and thallium. Arrangements for light modulation and colour television are also described (see Group XL (b)). This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 641,469, [Group XL (b)].
